JAMES S. 'PATTEN, OF BALTIMORE, MARYLAND.

VAXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 475,147', dated May 17,18.92.

Application tiled October 22,1891. Serial No. 409,466. (No model.)

To all whom it may concern:

Beit known that LJAMES S. PATTEN, of Baltimore city,in the State ofMaryland, have invented a new and useful Improvement inAxle-Lubricators, of Which the following is a specication.

My invention is an improvement in axles, and especially in that class ofaxles provided with a reservoir for oil, and constructed to feed oilfrom said reservoir to the spindle or bearing for the Wheel, seeking toprovide a novel cover for said reservoir; and the invention consists incertain novel constructions and combinations of parts, as will behereinafter described, and pointed out in the claims.

In the drawings, Figure l is a vertical longitudinal section of an axleprovided With my improvements. Figs. 2 and 3 are cross-sections onthe1ine0c ,Fig.l,showing the coverband adjusted to set itsopeningrespeotively into and out of register with the reservoir; andFig. 4 shows a somewhat different construction from that shown in Figs.l, 2 and 3.

The axle A is provided with a reservoir B, adapted to contain oil, andin the construction shown the spindle portion of the axle is grooved toreceive a rod, which extends into the oil-reservoir, and means areprovided for reciprocating such rod as the wheel turns on the spindle,so that the oil inthe reservoir will be supplied to the spindle orbearing as desired. The box C is fitted on the spindle and extends atits inner end nearly to the reservoir B, and bears at such inner endagainst a shoulder a. The cover D for the reservoir encircles the axleand lits over the reservoir, as shown. This cover D is in the nature ofa band or sleeve and is provided with an opening d, which is movableinto and out'of register with the reservoir. When the cover D is movedto set the opening d into register with the reservoir, as shown in Fig.l, the reservoir may be filled through such opening, and if the cover beadjusted to the position shown in Fig. 3 the cover will close thereservoir, as will be readily seen.

In securing the band in place it is preferably threaded internally andturned onto threads formed on the axle, as shown most clearly in Fig. l,and when the cover-band is turned tightly up against the shoulder l theband will be held in such position to close the reservoir, as Will beunderstood from Fig. l. In turning the cover-band a Wrench similar to anordinary hose-Wrench, having a point or prong to enter the opening OZ,may be employed.

While it may be preferred to thread the cover-band onto the axle, it isobvious that, if desired, it may be simply fitted on the axle, as shownin Fig. 4, Without threads, and be held with its opening d ont ofregister with the reservoir by means of a clamping-screw turning in theopening cl and arranged to bind against the axle, as shown in said Fig.el.

At its outer end the cover-band is formed at D to fit over the inner endof the box and projects slightly into the hub, thus forming an efficientsand-band, as will be readily understood.

An air-vent may be suitably provided. In Fig. l it is shown as providedby cutting out the Whole or part of a round of thread leading to theopening d.

Having thus described my invention, what I claim as new isl. An improvedaxle-lubricator, substantially as described, comprising the axlechambered to form an oil-reservoir and having along said chamberedportion external threads and the cover consisting of a band havinginternal th reads meshing those of the axle and provided with an openingmovable into and out of register with the reservoir, all substantiallyas and for the purposes set forth.

2. The improvement in axle-lubricators,'subr stantially asdescribed,consisting of the axle havinga spindle portion and providedwith an oil-reservoir and an opening or passage leading from saidreservoir to the spindle, the box fitted on the spindle of the axle, andthe coversleeve placed on the axle over the reservoir and having anopening which may be set into or out of register With the saidreservoir, the outer end of the cover-sleeve being fitted over the innerend of the box, all substantially as and for the purposes set forth. l3. In an axle-lubricator, the combination, substantially as described,of' the axle having a reservoir, the box fitted on said axle, and thecover-sleeve or baud fitted on the axle over said reservoir and alsofitting at its IOO outer end over the inner` end of thebox, suchopening* movable into and. ont of register with xo sleeve or band beingprovided with an openthe reservoir, and the box fitted on lbhe axle ingmovable into and ont of register with the and fitted at its inner endWithin the outer reservoir, all substantially as and for the purend ofthe cover sleeve or band, substantially 5 poses set forth. as set forth.

4. In an a-Xle-lubrioator, the combination of JAMES S. PATTEN. the axlehaving a reservoir and provided with Witnesses: threads, thecover-sleeve or band threaded on MoRToN SCHAEFFER, v

the axle over the reservoir and having an B. E. P. CRAMPTON.
